SN1 reactions follow the mechanism of 1st order kinetic whereas SN2 reaction follows the mechanism of 2nd order kinetics. There are two steps involved in SN1 reactions whereas only a single step is involved in SN2 reactions. towbar bristolThe SN1 reaction is a substitution reaction in organic chemistry, the name of which refers to the Hughes-Ingold symbol of the mechanism. "SN" stands for "nucleophilic substitution", and the "1" says that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on the substrate and zero-order dependence on the nucleophile.
